Under warranty, apple replaced the logic board. One day later, same problem is immediately back. Limping by with a workaround is not good enough. I need a solution or a different system. Anybody out there actually resolved this problem ? Not just a workaround? Apple? Hello?

After a replacement logic board (first) and top case (second), my issue persisted. I expect that it was related to heat management, fan activation, etc, although the fans worked, tested ok, and the thermal sensors in the battery/top case didn't fix the problem. Silverlight would cause the problem immediately, but it was by no means unique to that software. Apple finally resolved my issue with a *new* solution. After three work weeks without stability, ~15 hours on the phone, and ~500 miles driven here and there and everywhere, and a full restore from time machine, I'm back in business. Must have been a hardware problem.

Earlier in this thread I reported that I was getting the same issues with my mid-2012 macbook pro. These became more and more frequent and sometimes after the crash I was unable to boot (even after resetting the SMC and PRAM). Only after the passage of a few hours would the machine boot.

I took my machine to my local apple store five days ago. After a day they reported that it needed a new logic board. After another day they reported that it needed a new top case. I was told that it would be available for collection after five days.

When I went to collect it, I was told that they had decided to replace it with a new macbook pro. No explanation was given for this and to be honest I wasn't going to question it. Unfortunately, they're out of stock so I now have a "loner" machine for 3 weeks.

Fingers crossed this setting is working for me too... so far so good after a few days. Previously I was getting a GPUPanic every day on a Mid 2012 MacBook Pro. AppleStore ran a test and no hardware issues / fresh install of Mavericks didn't resolve the problem

I've been having the same issue with my mid-2012 MBPR for the last couple of months but its been almost unusable since upgrading to Yosemite.

I've since disabled the auto switching and as well I downloaded gfxCardStatus and I'm only running on the integrated Intel card. it seems to be functioning ok but I will be wanting to get it fixed as soon as get back in country.

Just had a GPU Failed kernel panic on my 2012 rMBP. Rather, I had a series of them seconds apart, according to Console. It's the first time I've seen this and I'm running the release version of Yosemite.

Is the consensus that this is a hardware problem fixed by adding thermal paste? If so, I'll take me rMBP in as soon as possible. I'd rather get the additional thermal paste and mitigate any heat-related damage before I get the GPU panics regularly.

I have been to Humac (Authorized Apple Retailer, Denmark) who told me to do a clean install cause that was what their mechanics would do. If it doesn't help i had to go to them again.

My warranty runs out the 19/1 2015 so i don't have much time to run.

I did the clean install but i still have the same issues. I tried some of the "tricks" or walkarounds from this thread which actually helped me.. i disabled the automatic switching between graphics which helped quite good but i don't see that as a permanent solution.
